For Environmental Using Chemical Pumps Environmental pollution will cause direct damage and impact to the ecosystem, such as desertification and forest destruction, and it will also cause indirect harm to human society. Sometimes this indirect environmental effect is more harmful than direct harm at the time. Difficult to eliminate.

Environmental pollution problems have occurred to varying degrees around the world. The areas with global impact include atmospheric environmental pollution, marine pollution, and urban environmental problems. With the globalization of the economy and trade, environmental pollution is increasingly showing an international trend. The problem of the transboundary movement of hazardous waste is an outstanding manifestation in this regard.
This requires us to analyze according to the causes of environmental pollution. Water is used more or less in various problems, even directly. In the process of treatment, we choose suitable water treatment facilities according to the type of environmental pollution. ---Pump
Using electric filters to check impurities, imperfect grains, and pure grains (quality) rates
Impurities refer to substances that have neither food quality nor grain or oil quality, or dissimilar grains. Refers to non-food value substances, and the specific provisions of the standard grain and grains of different types, absolute sieve material under the screen. The amount of impurities in food or oil depends mainly on harvesting, the degree of cleanup after harvesting, and storage and transportation. Imperfect grains refer collectively to food oil particles that are defective but still have food value. For example, worm-eaten grain, disease-plaque grain, germinated grain, moldy grain, damaged grain, frostbite grain, bake-injured grain, or unrefined grain, but still have edible value of grain and oil. As the name suggests, pure grains are imperfect grain grains that do not contain impurities and have no food value.
The methods and precautions for checking the impurity, imperfect grain, and pure grain (mass) rate using a motorized filter are as follows:
1 set of good sieve layer: according to the quality standards set in the sieve layer;
2 According to the provisions, weigh the sample into the upper sieve, cover the sieve cover, and place it on the electric filter;
3 Turn on the power, turn on the switch, select the sieve automatically to the left and right sieves for 1min (110 to 120 rpm);
4 After a few moments of sieving, pour the oversize and undersize into analytical trays and petri dishes (or miniplates), respectively.
